研究了异相应变和非同步应变对低周疲劳的影响。对7075-T6铝材薄壁管状试样进行了拉压和扭转两种双向应变作用。两个菌株之间的相位角分别为0°、30°、45°、60°和90°。研究发现，在低周疲劳范围内，异相循环对失效模式有影响。提出了基于三维应变中最大总应变的分析方法来处理低周疲劳中的“非相”应变。
The effects of out-of-phase or nonsynchronous straining on low-cycle fatigue was investigated. Biaxial strains were imposed on thin-walled tubular 7075-T6 aluminum specimens by tension—compression and torsion. Phase angles of 0 deg, 30 deg, 45 deg, 60 deg and 90 deg were applied between two strains. It was found that out-of-phase cycling has an effect on the failure mode in the low-cycle-fatigue range. An analysis based on the maximum total strain in three-dimensional strain is proposed for treating “out-of-phase” straining conditions in low-cycle fatigue.
